ESPECIPICAI'ION forming part of Letters Patent No. 391,678, datedOctober 23, 1888.

Application filed Decemherlil, 1887. Serial No. 257.802. (No model.)

To aZZ whom it 72mg; concern:

Be it known that I, VVILLIS BENNER, of New York city,inthe county ofNewYork,and in the State ofNew York, have invented certain new and usefulImprovements in Shutter Working and Locking Mechanism; and I do herebyde' clare that the following is afull, clear, and exact descriptionthereof, reference being had to the accompanying drawings, in whichFigure 1 shows a view in perspective of a shutter with myshutter-working attachment applied thereto; Fig. 2, a plan view of thesame with the top of the mechanism-containing casing removed; Fig. 3, avertical section of the same on line mcofFig. 2;Fig. 4,21 detail planview of the shutter-working mechanism with a different form of locktherefor, and Fig. 5 a sectional View of the same on line y y of Fig. 4.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to provide certain improvements in shutterworking mechanism, whereby a shutter or blind can be opened or shut andlocked in any position desired from the inside of the casing withoutopening the window; and to this end my invention consists in the shutterworking and locking mechanism, and in the construction, arrangement, andcombination of the parts thereof, as hereinafter specified.

In the drawings, A designates the frame or casing of a window, which canbe of any de sired form and construction, and B designates the shutterto be worked.

In the sill or lower side of the casing is set a flat box or frame, 0,preferably of metal,for receiving and supporting the operativemechanism, to be described hereinafter. The top or lid of this box orframe is best made flush with the outwardly and downwardly inclinedupper surface of the lower casing side in which the frame is set. Theouter side of the flat box or frame 0 is removed, as indicated in thedrawings, so as to make room for the passage of the parts of themechanism connected with the shutter.

At one corner of the box or frame 0, and near the outer side thereof, isthe bevel gearwhcel D, whose arbor D is journaled below in the bottom offrame 0 and above in the bridgepiece E, attached to the frame in anydesired way. Attached to this wheel is an arm, F, connected at its outerend with the shutter B by means of the link G, which is pivoted at oneend to the shutter and at the other to the arm. Said arm is preferablynot straight throughout its length, but near its outer end bends outwardand forward in the direction in which the arm swings from the frame 0 inopening shutter B. Vhen the shutter is closed, as shown in Fig. 2. thearm is swung within the box or frame 0 and the link G extends backwardand outward from the curved outer end of the arm to its point of pivotalconnection with the shutterthatis, the link extends at an angleoutwardlyin the general direction in which the shutter is to be moved asit is being opened. The curvein the arm Fallows the outer end of the armto be swung well around outside of the shutter when the latter is swungopen and back, as shown in dotted lines in Fig. 2. The outer end of thearm can then thrust the link so far as to swing the shutter to the limitofits swing upon its hinges, or back against the building, if desired.

For turning the gear-wheel D to swing arm F and open, close, or adjustthe shutter, as wished, I have provided the gear-wheel H, meshing withsuch wheel D and fixed on an arbor or shaft, I. This arbor or shaft isjournaled, as shown,in portions of the box or frame 0, and extendsinward therefrom through the casing of the window-sill. On its inner endis a handle or head, I, for convenience in turning it, as desired.Obviously, with the construction dscribed, the shutter can, by turningthis handle one way or the other, be opened or closed easily andquickly.

To provide for fastening or locking the shutters open or shut, or in anydesired position, I, have two forms oflocking meehanism,either of whichcan be used.

The form shown in Figs. 1, 2, and 3 consists of a pawl-lever, K, pivotedto the shaft I, and carrying a lug or pawl, 7c, adapted to engage theteeth H on the fixed circular rack L. As shown in the drawings, thislever is at its pivotal end forked to embrace a collar, 6, fixed onshaft I, and its opposite fork-arms are both pivoted to the said collar..Vith thepawllever and fixed rack, if the shaft I be turned to bring theshutter B into any desired position-open, shut, or partially open saidshut ter can be locked from the inside against any movement by simplymoving the pawl-lever to bring its pawl into engagement with therack-teeth Z Z. \Vhen the shutter is to be moved again,the pawl-levercan be moved out of engagementwith the rack by a finger of the handgrasping the handpiece or head I.

In the form of fastening or locking device shown in Figs. 4 and 5 thepivoted pawl is dispensed with. The gear wheel H, which is fixed onshaft I and which meshes with and rotates wheel D, is then provided witha series of gear-teeth, h h, on its inner side, or side toward theturning-handle I. Attached to the ends of two parallel rods, M M,extending on opposite sides of and parallel with shaft I, is the bar orplate N, having on its outer side teeth or projectionsnn, adapted toengage the teeth 7th on wheel II when the plate is moved toward wheelII, as hereinafter described. Said plate preferably extends diametrieally across the inner face of wheel D, and is provided with a suitablecentral opening to accom modate thehub h ofsueh wheel. The rods MM passloosely through suitable openings in the inner side of boX or frame 0,and thence inward beyond the inner side of the window-casing. Upon suchinner side of the casing I prefer to place the plate 0, provided withopenings 0 0, through which the rods loosely pass. The rodopenings inthe boX or frame 0 and this plate will then keep the rods parallel toeach other and the shaft I, while leaving them free to be movedlongitudinally inward or outward. On the outer end of each of the rodsis a head, m, and loose on the shaft I is a sleeve, P, having the twoparallel collarspp, adapted to engage the inner and outer sides of theheads at m on rods M M, and also the cross-bar or handle P, parallelwith handle I on shaft I. One or more springs, It, on the boX or frame0, engaging the bar N, force it normally inward, so that its teethengage those on the wheel H and lock the latter from turning. The handleI? then occupies the position shown in full lines in Figs. at and 5.

\Vhen the shaft I is to be turned to operate the shutter, the handles Pand I are grasped at the same time. Such grasping will draw the handle Ptoward handle I, and, through the engagement of collars p p on thesleeve 1? with heads at m on the rods M M, will draw the bar N away fromwheel I-I, so as to leave the shaft and wheel free to be turned by rotation of handle I. The handle P, being grasped with handle I, is ofcourse turned with it. \Vhen the shaft has been turned to adjust theshutter as desired, the handle P is released, and the springs R R atonce throw the toothed bar N into engagement with the teeth h h on wheelII, so as to lock the wheel from further rotation in either direction.

Having thus described my invention, what I claim is- 1. In a shutteroperating mechanism, in combination with the curved swinging arm, a linkpivotally connected with the outer end of the arm and with the shutter,substantially as and for the purpose shown.

2. In combination with the shutter, a rotary wheel, and a curved armcarried by the wheel, a link connecting the outer end of the curved armwith the shuttensubstantially as and for the purpose described.

3. In combination with ashutter and a shaft projecting within the casingand provided with a handle by which it can be turned, a rotarygear-wheel, a curved arm carried thereby, a link connecting such armwith the shutter, and connecting-gearing between the shaft and thearm-carrying wheel, substantially as and for the purpose set forth.

4. In combination with the shutter, the curved swinging arm and the linkconnecting the outer end of the arm with the shutter, a rotary shaftprovided with a suitable handle, whereby it can be turned from withinthe window-casing, connecting-gearing between the shaft and the curvedarm, and a lock for the shaft, substantially as and for the purposespecified.

5. In combination with the shutter, the swinging 'arm and the linkconnecting the arm and shutter, the rotary operating-shaft provided witha suitable turning head or handle, connecting-gearing between the shaftand arm for moving the latter as the former is rotated, a pawl-piececarried by the shaft, and the stationary rack, substantially as and forthe purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this5th day of November, 1887.
